Superstructure 3

Superstructure 3

I contemplated various ways to removably attach the superstructure to the deck so as to allow access. The outcome is that the structure is held onto the deck by four pegs that engage in corresponding holes in the coaming (see next page). All the pegs face aft, so the structure is placed on the deck a few mm forward of it's location and then pushed aft to engage the pegs to the coaming.

To secure it there a screw is fitted in the arrangement seen at lower middle here. When wound in this bears on the back of the coaming so the structure can't shift forward and come loose. The screw is finger twiddled and the head is finished as a plastic cylinder which will, perhaps with a bit more work, pass for a fitting or vent of some sort.
